Inversely assembling process for standing stay wire V-type tower

Abstract

The invention relates to an inversely assembling process for a standing stay wire V-type tower. The process comprises the following steps: assembling a standing door type rack, assembling the head part of the stay wire V-type tower and mounting point rope systems, inversely assembling the stay wire V-type tower, and placing the stay wire V-type tower in place. According to the process, the head part of the stay wire V-type tower is lifted to a certain height above the ground through the door type rack first, then a lower tower segment is assembled below the head part of the stay wire V-type tower, after that, the head part of the stay wire V-type tower continues to be lifted, so as to continue to assemble a second lower tower segment, and the assembling continues until tower legs are assembled. In the process, the door type rack is adopted to inversely assemble the standing stay wire V-type tower in a decomposing manner, so that the load on an appliance is greatly reduced and the hoisting operation is safe and reliable; and the process is suitable for inversely assembling a large-scale stay wire V-type tower and is also suitable for occasions unsuitable to adopt large-scale cranes for operations. The process doesn't need a large-scale crane and is little limited by transportation, and a door type rack hoist system formed by combining machines and tools used frequently for daily construction can replace the large-scale crane to fulfill a task.

Description

【Technical field】 [0001] The invention relates to an iron tower for power transmission and transformation, in particular to a process for flip-chip assembly of a pull-V tower. 【Background technique】 [0002] In large-scale high-voltage power transmission and transformation projects, tall and heavy-duty cable towers are often used. The guyed V-shaped iron tower (hereinafter referred to as the pulled V-shaped tower) is a commonly used guyed iron tower. The traditional pulling V tower often adopts the method of erecting as a whole (that is, the iron tower is first assembled on the ground as a whole, and then the iron tower is erected from the ground with a herringbone pole). However, this overall erection process is only applicable to relatively small La V towers. For tall and heavy pulling V-towers, if the traditional pulling method is adopted, the force on the tool system will be huge, exceeding the carrying capacity of most commonly used tools and tools, and the safety ris...
